组合叠合箱现浇网梁楼盖结构的施工工艺与应用

随着人们对大空间需求的提高,网梁楼盖结构可以实现大跨度、大空间,梁板高度相同,且非预应力形式能够达到33 m跨度.该结构施工配套模板平整简单、节省,箱体单体分体质量轻,便于运输和组合安装,施工工艺简单,利于缩短施工周期.因其自重轻、承载力高,可选择较大的结构高度形成梁板组合截面;自重轻则产生的地震力较小,因此其抗震性能好.整体刚度很大,挠度变形、转角变形很小,对楼盖边梁的扭转作用比普通楼板要小得多.

Design and Construction of Combined Composite Box Cast-in-Situ Net Beams and Floor Structures

Because of the increasing need for the large space,net beams and floor structures may realize large span and large space with the same height of the floor and beams.At present,the span of the unprestressed concrete forms can be 33 meters.The construction matching templates of this structure are even,simple and economical.The monomer fissions are light and easy to transport and install.The construction technology is simple and conducive to shortening the time of the construction.Owing to the light weight and high bearing capacity,it can choose bigger structures than the normal ones,and also because of its light weight,the seismic performance is good.The overall rigidity is hard,the deflection and angle deformations are small,and the torsion effect of the floor＇s boundary beams is much less than the normal ones.
